I am selling my cargo bike trailer I fabricated out of steel. I designed the trailer to haul lumber, but after using it only a handful of times, I ended up getting a car, so I no longer need the trailer. The frame of the trailer is 5 feet long, with 2 sets of dropouts for the wheels, 1 at 30" back, and another at 48" back. If you put the wheels on the further back set of dropouts, you can haul 8 ft boards, no problem. The wheels are spaced about 14 1/2" apart, meaning you have room for 12" wide boards between the wheels. The frame is welded together using 1/16" steel square tubing, making it lightweight, yet extremely strong and rigid. The hitching mechanism is made by Burley, and attaches to the left side of the rear wheel axel, similar to their bicycle trailers. I painted it with the most eye catching color I could find, bright green, and then afterwards with a glow in the dark clear paint. I'm asking $500 for the trailer. If you look up similar cargo trailers, they run you upwards of $1300, so I think this is a fair price.
